The activities of the Yokohama Chapter of Young Astronauts Club-Japan are introduced as an example of space education. The main theme of the workshop is atmosphere of the earth. In the workshop, they learned of the history of the earth, compared the earth with other planets, studied the material cycle, and gained a good feel for the course of the earth up to the present. The workshop shows that thinking "on a universe scale," the most essential characteristic of space education activities, produces great educational effects.
